10 CALCULATING AIR CONDITIONER DISTRIBUTION
10.3 Calculating loaded distribution
Data fl ow
[Out door unit]
Calculation:
power T2
gas TG
gas for power generation PG
standing-by power TS
energy saving-consideration power T3
energy saving-consideration gas TG3
power at night by ice heat accumulation TC night
high-pressure saturated temperature HPS
A T2, TG, PG, TS
T3, TG3, and TC night
[Adaptor]
All through
[Intelligent Controller]
Setting:
Heater capacity H
Fan current added value B
Pulse unit @ e, @ g
•
Calculation:
* "f" means function. For example:
Operation capacity ratio D = f (SH, SC)
means that the operation capacity ratio is calculated using super heat SH and sub cool SC.
Calculation parameter
Indoor unit capacity (kW)
Indoor unit operation time
Indoor fan speed ratio (high, medium, low)
Outdoor unit operation ratio
(Power: detected using CT, Gas: neuro-calculation)
Standing-by power and various heater powers
Indoor unit loaded ratio (Calculated using the values
detected by multiple internal thermo sensor of indoor unit)
:parameters considered in distribution calculation
:parameters not considered in distribution calculation

B HPS
Calculation:
operation capacity ratio D = f (SH, SC)
fan speed converted value FI = f (actual wind speed)
super heat SH = f (E3, E1)
sub cool SC = f (HPS, E1)
Operation capacity PINb =
G T2, TG, PG, TS
T3, TG 3, and TC night
PIA = f (PS, T2, PINb, PINg)
PIA = f (PIA, TS, PS, W, H, R, B)
PGA = f (GIN, TG, PG)

CIN = f (D, FI, and PS)
G PINb

•
Power distribution ratio RPI = f (PIA')
Gas distribution ratio RGI = f (PGA)
•
Factor related to ice heat accumulation ICE = f (TC night, RPI)
Pice = f (Pc, @e)
•
Power usage PI = f (RPI, Pc, @e, ICE, Pice)
Gas usage GI = f (RGI, Gc, @g)
